The ArenaNet Blog features a discussion of underwater combat in Guild Wars 2 from game designer Jonathan 'Chaplan' Sharp, offering screenshots showing off underwater environments and weapons, as well as a full outline of how this will work. There are also new impressions of the game floating around, as ArenaNet recently demonstrated the upcoming MMORPG sequel to a bunch of sites, who got to experience this aquatic aspect of the game firsthand. There are previews on G4tv.com, Massively, MMORPG.com (where they also have an ArenaNet Studio Tour), and PC Gamer. There's also an underwater combat video on GameSpot, and Guild Wars 2 Slovenija has clips with a pair of dungeons from the game.
